HDMi to dvi on new mac mini does not work

You have to make sure that the cable is bi-directional and not uni-directional. Usually the cheaper cables are uni-directional.

Just unboxed my M1 mini and was surprised that it wouldn't turn on with my monitors. Tried it HDMI to DVI as well as through a USB-C dock and nothing lit up. Plugged it into my TV with HDMI, and sure enough, it worked.

Am I correct in my understanding that no HDMI adapters work and USB-C can only power one monitor? My problem is that I was planning to use 2 monitors, both of which are DVI, and from this thread, it seems like this is currently not possible with the M1 mini.

According to Apple specs HDMI to DVI should work with an adapter. No ifs, no buts. And it does not work with a brand new genuine Apple adapter. So it is BS to say that this is because DVI is such an old tech. And if one wants to have two monitors, apparently one has to be on the HDMI connector.

FWIW my Dell 2707 WFP does support HDCP on DVI (works perfectly connected to a Blu-ray player).

At this point Apple has to do either action:

• communicate on this issue and fix it with a software update ASAP (preferred)
• offer a free USB-C->DVI adapter
• take back and refund the computer

I've been fighting this for a month and am giving up. I have an open case that will stay open. I sent them the first mini that had the problem for engineering inspection (they could have just grabbed one off the production line, but I was trying to help). New machine = identical problems. Not to mention the problem where my setup falls asleep and system has to be rebooted daily. Or that the display routinely blinks black for a second or two when when in use. There is a chance they will fix some of the M1 mini display issues sooner or later IF it is software. If it is hardware - maybe they make a running change in production. The reality is there may not be enough people with problems for Apple to address this issue. I have a 2 year old open case because Time Machine does not support Mail as it should. I'll keep getting thread updates and updating the OS, but can't spend more time on this. Not trying to be Debbie downer, but manage your expectations. I love Apple and have been completely in the ecosystem since iPhone 1. But no question, customer support and dedication to solving engineering design problems have declined dramatically.

I have been down so many rabbit holes trying to connect my TWO 30" LCD Cinema Displays to the new M1 Mini. I'd given up on HDMI and had a Startech Displaylink Displayport to USB-C adapter going, but that just kept failing too for some reason (after working for a week). Finally found this thread, updated to 11.2 and RE-ORDERED the Apple HDMI-to-DVI adapter (after having returned it along with countless Amazon adapters), plug it in today--no dice. I wish someone could tell me if it's the HDCP-off parameter to these old monitors or what. If anyone has had any recent success, please let us know.

Displaylink driver the problem? HDCP? NVRAM? would SwitchRESX help? So many questions.

For now I am stuck with 1 monitor (connected via a USB-C to minidisplayport adapter, connected to one of the Minidisplayport-to-DVI adapters I've had for years now.)

Same thing here. Upgraded from 2014 mac mini to M1 and my existing HDMI to DVI cable/monitor doesn't work. Annoying but glad I'm not the only one. Going to store to get usb-c to DVI adapter now.

Thanks! That is apparently the first time somebody from Apple to recognize the problem - and even more important, it is supposed to be fixed with a future SOFTWARE UPDATE!

I have mac mini 2018 and I use it with usb-c to DVI-D and my monitor work only after login. Now 2 years later nothing change. OSX 11.2

THANK YOU APPLE FOR GREAT SUPPORT!

I'm having the same issue. I cannot get an HDMI to DVI connection to work. I've tried both an Amazon Basics HDMI to DVI cable and Apple's HDMI to DVI adaptor. I'm hopeful this will get in a future software update because Apple does claim that this will work on the Mac mini's tech specs page.

Super helpful - thank you for the post. I am one step behind you and pretty sure the next step they will want is to give me a new Mini. That did not work for you. Seems what we don't know is if this just affects a few Mini M1's, or all of them. Based on the # of posts here - not many posts when it comes to widespread Apple issues - my guess is maybe it only affects some Minis? I think my next step if (when) the new Apple HDMI-DVI adapter cable does not work --- is just register it as an open case and ask to be notified if/when they fix it via hardware or software fix. We have a year warranty on the hardware which should cover "not operating according to advertised specs" I would think...

I was just on the phone for the third time with Apple support. It seems that nothing has happened since my last call a couple of weeks ago. I had to tell half of what I have told earlier, then we tried a safe mode boot (with no help) and off it goes again to the "engineers". Didn't ask this time, but last time the support person found nothing about this problem in their system. Only some vague mention that use of USB-C is recommended. They'll contact me again next week...

Unfortunate but not surprising. There don't appear to be a lot of people with this issue. To consider a problem a priority, there needs to be hundreds or thousands of people with the problem. From this forum, looks like more like a few handfuls. So they either take their time, or it never gets solved. I have trouble tickets with Apple on my 2019 iMac for a different issue that are frozen in time, also for things that did not affect enough people for them to bother with..

Just for reference, same issue with a Mac mini M1 connected via HDMI->DVI cable to a Dell WFP 2707 monitor (1920x1200).

This monitor works perfectly connected to an old MacBook Air with a thunderbolt/HDMI adapter.

Well that's good news! Thank you for the update, it's useful to know that a solution is round the corner. As I currently have my MacMini working well on my Thunderbolt display via a Thunderbolt 3 adapter, I can afford to wait until the official release of 11.2. (I got the MacMini M1 to replace my wife's old MacMini i5 on an old VGA Formac screen but can't bear to let go of it yet!) I wonder why they can't just release the Firmware update as a separate entity to be going on with though?
